General Description
The TCM809 and TCM810 are cost-effective system
supervisor circuits designed to monitor VDD in digital
systems; providing a reset signal to the host processor,
when
necessary.
No
external
components
are
required.
The RESET output is typically driven active within
65 sec of VDD falling through the reset voltage thresh-
old. RESET is maintained active for a minimum of
140 msec after VDD rises above the reset threshold.
The TCM810 has an active-high RESET output, while
the TCM809 has an active-low RESET output. The
output of the TCM809/TCM810 is valid down to
VDD = 1V. Both devices are available in 3-Pin SC-70
and SOT-23B packages.
The TCM809/TCM810 are optimized to reject fast
transient glitches on the VDD line. A low supply current
of 9 A (typ., VDD = 3.3V) make these devices suitable
for battery-powered applications.
